In 1880, Rydberg worked on a formula describing the relation between the wavelengths in spectral lines of alkali metals. He noticed that lines came in series and he found that he could simplify his calculations using the wavenumber (the number of waves occupying the unit length, equal to 1/λ, the inverse of the wavelength) as his unit of measurement. He plotted the wavenumbers (n) of successive lines in each series against consecutive integers which represented the order of the l… WebDec 1, 2024 · Rydberg atom-based sensors for radio-frequency electric field metrology, sensing, and communications Published December 1, 2024 Author (s) MATTHEW SIMONS, Aly Artusio-Glimpse, Amy Robinson, Nikunjkumar Prajapati, chris holloway Abstract The recent redefinition of the SI bolsters the push towards quantum-based sensors.
